Ball Mills in the Mineral Processing Industry

Loading the Mill: The ball mill is loaded with the material to be ground and the grinding media (balls). The material can be fed into the mill either wet or dry. Rotating the Mill: Once loaded, the cylindrical shell starts rotating around its horizontal axis. Various mechanisms, such as gears, belts, or direct drives, can facilitate this rotation.
